Reply #32: Probably not a colostomy bag. More likely a urinary catheter leg bag.

If a colostomy bag were that full, it would be too heavy to stay adhered to the stoma (the opening from the intestine to the abdominal wall). Urinary catheter leg bags can be fastened to the thigh and are made of a heavy-gauge vinyl, and thus can hold 1-1.5 liters of fluid. Given that Evil Dick has a history of heart disease, there are drugs he might be taking that cause urinary incontinence (ie calcium channel blockers, antihypertensives, diuretics). Also, prostate enlargement is common in men Evil Dick's age, which can cause problems with urination.
That's my guess, anyway.
